Crane CheckStar Multi

Capacity 1 / 2 / 5 / 10 / 20 / 25 / 50 / 75 / 100 / 180 / 250 / 500 / 750 / 1400 / 3000 / 5000 Nm

Rotary Transducer with tri-colour Light Ring

The CheckStar Multi is the latest generation of Crane Electronics market leading CheckStar in line rotary torque transducer. It raises the standard for dynamic torque and angle measurement of all continuous drive and impulse tools, with proven reliable performance in thousands of applications worldwide.

If angle is specified, the CheckStar Multi rotary torque transducer will include an angle encoder giving 0.125° resolution (720 PPR). It also incorporates a light ring, giving the user visual feedback of the status of a tightening, when used with a Crane readout or data collector.

The CheckStar Multi fits in line between the assembly tool and the fastener, measuring the actual torques applied and angular rotation of the fastener, under production conditions.

Whatever the vibration and shock loads experienced, CheckStar Multi’s patented contact system ensures a connection is always maintained between the readout and the strain gauges. Inferior systems suffer from “brush bounce” that leads to unreliable torque readings.

The low inertia design of the CheckStar Multi ensures accurate and repeatable measurement of high speed transients, such as the point of shut-off on continuous drive tools and the pulsing of impulse tools.

Using on-board intelligence the CheckStar Multi is automatically recognised by a Crane data collector or readout device, eliminating set-up errors and enabling logging of serial number against measurements for complete traceability. The CheckStar Multi can also be used where a user needs the advanced features of the transducer but already has a data collector or readout device from another manufacturer.

Any torque equipment is recommended to be used mainly in its medium range. If you had to work close to the maximum load capacity regularly, a larger model should be chosen to prevent risk of overtorquing.
